This is probably due to you installing to point a) Upgrading to a pre-release version of Ubuntu.
I wouldn't recommend doing it, as you need to uninstall ubuntu-desktop to update.. but then when you try reinstalling you'll fail. The main reason for this is that fast-user-switcher applet is not yet in a state to upgrade. This is due to the current version in the repositories (constantly being updated and changed, as is the state with pre-release software). I'd recommend that you run `apt-get update` again to pull the latest changes - it may now let you upgrade. However, remember, this is _unstable_ software, so use it with this in find. -- Can not upgrade https://bugs.launchpad.net/bugs/327759 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
